Question

if the max & min resultants of thetwo vectors ae 7 & 1 respectively.find the resultant when they are acting at right angles to eachother​

Answer 1

Answer:

| Fmax∣=7 N⇒F1+F2=7

∣Fmin∣=1 N⇒F1−F2=1

⇒F1=5N and  F2=4N

When, θ=90degree

F resultant= root F1^2+F2^2+2F1F2Cosθ

               = root5^2+4^2+0=root 41N
